REW doesn't recognize my player

[jeb109]

Trying to set up REW. Player not recognized.
In Preferences, Output window just shows [1: Not connected 1].
Equipment: LG GRAM laptop running Windows 11. Oppo UDP205 is player. Connecting through HDMI port on laptop and Oppo.
Laptop and Oppo are recognizing each other- I get computer screen on TV that is also connected to Oppo through another HDMI port.
UMIK microphone connected through usb port on laptop is recognized in REW Preferences (same window where I'm trying to set up Player.)

Probably worth posting a screenshot of the soundcard preferences, to see what device the "Not connected" output belongs to. There is a guide to setting up HDMI and a USB mic on Windows in the downloads.

Player is recognized if I change from ASIO to JAVA.

If you are using ASIO4All you will need to select the input and output devices in the ASIO4All control panel, as shown in the guide I linked.
